To all whom it may conce-rn:

YBe it known that I, CHARLES A. LIND- srnnr, of Allegheny, Allegheny county, Pennsylvania, have invented a new and useful Improvement in Carv Construction, of which the follow-ing is a full. clear, and exact description. reference being had to the accompanying drawings, forming part ot this specification. in which* Figure 1 is a planview of av portion of a. car embodying my invention, with parts broken away; Fig. 2 is a side elevation of the same with the,side sheet partially broken away, and some of the parts in section: Fig. is a transverse section oi. a larger scale, with one of the doors in open position; Fig. v4 is a View partly iii-section showing one of 'the bolster'diaphragms; Fig. `5 is an end View vof the same with theside sheet re- "move'dg Figs. 6 and are-views corresponding' respectively to 'F igs. 4 and 5. but showing amo'dification; F igsfS and 9 are views similar to Figs. 4 and 5, but showing :1nother modification; Figs. 10 and 11 are views corresponding respectively to Figs. 4

land 5, butl showing a third modification;

' showing a further modification; Fig. 23 is' Fig. 12 is a View of one end portion of one of the diaphragme or cross-members showing another modification; Fig. 13 is an end view or the construction shown in iF ig. 12 with the side sheetremoved; Figs'. 14 and 15 are views similar to Fig. 4, but showing other modifications; Fig. 16 is an end View of the construction shown i'n Fig. 15 with the side sheet rem ved g. Fig'. 17 is an end view of one-halt' of the car, as seen from the inside; Fig. 18 is a section on the line XVIII-X'VIH of Fig. 17 .-with thedoor in closed position; Figs. 19 and 20 are .views similar to Figs. 1T and 18, showing a modified construction: Fig. 21 is anend view of another construction ofl diaphragm; Fig. 22 is a cross-sectional View of one-half of the car an Vend View of the diaphragm shown in Fig, 22 with side sheet removed;` and Figs. 24, 25, 26, 27 and 28 are detail views. showing different Ways -of' constructing the cross members or diaphragms.

My inventionrelates' `bottomsprovided withl downwardly opening fdoors, `and t--has particular relation to fthe .lading is caused to be discharged over to theclass of steel cars, particularly'gondola cars, having flat discharge ot' the load at the sides of the'cars. In this type of cars, with the diaphragms as heretofore constructed and arranged, ,the

downwardly opening' doors commence to discharge vtheirpload shortly after they com-- mence'to open, lthe lading alling over the side edges of the doors and underneath the Patented Api-i1 13, 1909, v

car, and lodging on the projecting angles or flanges on the diaphragms.

My invention consists in providing' means whereby this objection obviated and the the free or outer edge portion ofthe doors when opened. and is prevented from falling over -t'he side edges thereof. To this end, 1 arrange the doors between a series of transversely arranged crossmembers or diahragms having vertical smooth outer sur- ^.aces, free 'from projections in the path of L', and between the lading when discharginV -and in -close proximity 'to-which 'thedoors move in opening, and which extend as integral portions ot' the diaphragm toa sut'- tic-ient depth to form guards for the side edges of the doors throughout the .major portion of `their lengths when opened.

'My invention also consists in the novel construction, of the cross-members ordinphragms whereby they form guards for the doors in the manner described, and whereby. they also` provide interior spaces for the location of any suitable door-operating mech anism.

.The diaphragms may be of various formsv ofconstruction, but in general they consist in a deep .hollow box-likel structure extending integrally down land outwardly to the dotted :llnes 'a sufficient distance to form guards for the doors when opened for themajor portionv of their lengths, or to a y'point in the verticalplane'of the carrails,

The hollow box-like form of the diaphragme lnot only ives them greatstrength, but it also provil es interior spaces in which the door-operating connections in accordance with other inventions which will .form the subject-matter of other applications, may be arranged and protected. f.

In `the forinshown in Figs.

' The constructionshown in Figs. 10 and 11.isl similar to that shown in Figs.. 8 and 9. exceptthat internal reinforcing angles 23 a1eprovided. j

' In the construction shown in Figs. 12- and 13, the side sheet 2 is bent inwardly' at its lower end underneath the'shedding strip 17, and is secured to anoles :211, 4to which the lower end portions "oi the starke tiring-es 15 and also the bottom member are secured.

The construction shown in F ig.'1fl is generally similar to that shown inligs. V12 and used inplace 13, except theta Z-bar 25 is of the angle '24, to the bottom flangey ot secured at its upper' outer ends."

The constructionshown 1n Figs. 1 5 and 16, is similar to thatof F ig. le, except that tom, as shown at`19 Y downwardly -turnedl .which bar klthe reinforcing channel 18"is the Z-bar 25 is omitted, 'andthe end-portiOIvlS '12,? are secured directly to the down ward extensions of the stake irons.

Figs. 17 and'18 show'one form of con-A struction of-one offthe end sills or diaphragms. This is' shown as 'formed by. a: strip or plate whose upper edge port1on27 is secured tothe end sheet 3, and forms an end vshedding strip 'having an overhang 28, below which it is carriedlvertical-ly downward to form the guard for the edge of the end door, its-function being similar to the side members of the other diaphragme This plate. is reint'orced by means ot' .the

phragin is shown with the exception that instead ot the reinforcing brackets Q9. `the conand along their lower edges, inwardly projecting flanges along their upper edges and W y stitlening means interposed between Said In rigs. lt) and i0 a similar end d1atinuous reintorcing members 3() and Btl-t are placed between the vertical portion of the diaphragm. and the end sheet 3 ot' the car.

Fig. 2l shows a diaphragm formed by a single plate 3l, which is bent to form its top and side members, with angles 31a riveted thereto.

Figs. and 23 shows diaphragins formed of two channel members and 33 having their horizontal flanges overlying each other to' form the top and bottoni members of' the diaphragm.

Figs', 25, 2G, 2T and '2S show different ways of constructing the upper portion of Fig. 2t shows a construei tion similar to Fig. Q1, formed of a single the diaphragm.

plate with a tioor'plate 16 riveted thereto.

and with inturiied end `flanges 3l; Fig. shows the diaphragm formed of two ineinbers as in Figs. 22 and 23. with the floor plate riveted thereto; Fig. Q6 shows internal angles lfor carrying the floor plate, and the end flanges S-l bent outwardly instead of inwardly, and Fig. 2T- shows the upper edges of the side members bent outwardly to form flanges 36 to support the floor plate.

In the construction shown in Fig. 2S a separate lchannel 3T, either rolled or pressed. is riveted to the side plates to form the top portion.

-Throughout the several forms herein described it is, of course. obvious that separate angles may be employed instead of the intel gral flanges described without departing i l extending' below the car i'ioor to forni a door from the scope of the invention, and wlieie the term flange i is used in the claims it is desired to cover either integral or separate strengthening or connecting strips.

It will be obvious that various other forms of construction may be employed within the i n a dump car. a beam or cross-bearer' consisting of metal diaphragms having outwardly projecting flanges at their inner ends diaphragms at their outer ends.

l. ln a dump car. a box bea'ni or crossbearer consisting of metal diapliragins tied together and extending from longitudinal center to side of the car, having strengthening flanges extending in one direction at its lower inner end portion and having strengthening flanges extending in the opposite direction at. its upper outer end portion.

5. ln a dump car.' a beam or cross-bearer consisting of a pair ot' metal diaphragins having inwardly extending flanges along their upper and'outer edges, and a perforated tie member interposed between said members at its forward end.

T. A car having an end shedding strip provided with a vertical depending portion extending below the car floor to form a door guard, and a reinforcing member between the depending portion and the end sheet of the car; sulistantially as described.

A ear having an end shedding strip provided with a vertical depending portion tical depending portion extending below the :ar floor to form a door guard, said depending portion being spaced from the end sheet of the car; substantially as described.
